Using remote coolant thermo for oil??
owelly - 2/8/07 at 05:01 PM

I think my oil is getting hot. I have a cooler and remote filter all bolted in ready for some pipes but then I spotted this in my hand

the inlets/outlet are the right size but it's off a FZR600. And it's for the coolant.
Any ideas folks?? Or should I just plumb it in a see what occurs?

Wouldnt the coolant opening and closing temps be too low for oil??

I don't know. That's one thing that concerns me. But if it did open too early, it would be better than not having one!

Water runs at about 10-15psi max and no real pressure at the temperature the stat opens, oil by comparison runs at 60-80psi average and will be higher pressure when the oil is cooler. That could cause several issues including the stat opening under pressure / not being able to open due to too much pressure (ie the spring isnt strong enough), it could also lead to leaks in the seals that arent designed for oil / high pressure, and you may have problems holding hoses of that size on at that pressure with just jubilee clips etc.

Considering the implications of it failing, definitely not worth risking IMHO.

All my oil hoses are held on with good quality worm drive clips so that's not really an issue. The point about the pressures is a very good point!! I'm off to try and pressurise the thing to see if I can get it to pop!!

But I have just spotted a 1/2" solenoid valve which I could use...........

How will that work? Surely you need something that bypasses the cooler when its cold, then brings the cooler into the circuit at a certain temperature. A solenoid valve (from what Im envisaging) will act like a tap and simply open or close to allow fluid through or not?

I could Tee the cooler into the system and when up to temp, the solenoid would open and let the oil through. Only some of the oil would go through but I also have another solenoid valve which could close to divert the oil if you see what I mean?
I've had the thermostat unit upto 90psi with no trouble (with air) and I'll drill a small hole in the thermostat so the pressure is equal on each side of it and see what happens......
I have several pressure gauges plumbed in around the engine so I should spot any lack of pressure before it goes pop!

Why not plumb in the oil cooler as normal and just tape it up when the weather is cold?

That's exactly what I do with my radiator (without a stat).

I'll just plumb it in as you suggest Coose. Not that I'm taking advise from you.....your car broke......

Ah, but it's nearly fixed! 'Cept for this....

Oh dear....
Oh dear....


So, out comes the TIG welder again!

Just fit the oil accumulator and the oil cooler, and a big filter, that will increase the amount of oil you have, and if you mount them all at the front, cool the bugger too.

of fit a water to oil cooler

I've just plumbed the cooler in as normal. But do to a lack of fittings and an urge to get mobile, I've left the remote oil filter for another day. I do have one or two of those water/oil coolers but the extender tube is the wrong thread.

a man of your ability and complete stupidity should be able to overcome a small problems like that
